CPF-D series Clo2 generator is flowrate control on-site generating system. It can add clo2 aqueous directly towater pipe with simple, safe, reliable, stable operation. It can adjust thedosage of clo2 aqueous through receiving 4-20mA signal provided by the flowrate sensor. The way of clo2 producing: 5NaClO2+4HCl = 4ClO2+5NaCl+2H2O. Technology: Use sodium chlorite and hydrochloricacid as raw materials, transmission of raw materials through two metering pumpsto the reactor, produce the concentration of more than 95% of high-puritychlorine dioxide solution added to water for disinfection. It can automaticallyadjust the dosage of clo2 solution through flow control and residual chlorinedisplay system. When lack of raw materials, the liquid level alarm system willgive audible and visible alarm signals and automatically cut off the powersupply of equipment. The entire control system use PLC as the core, on-siteparameters setting through the touch screen and remote control through the computer,to realize high-performance automated management of Disinfection System. Rawmaterials conversion rate is more than 95%.
